- W2978114906 abstract "Introduction: Diarrheal disease is still known to be one of the most common cases of morbidity and mortality. The identification of the infecting microbe can be important for the prevention of epidemics and severely ill and immunocompromised patients. However, it may not be cost-effective to perform stool cultures for all patients with acute diarrhea. The aims of this study were to investigate the positive rates of stool cultures and to identify the predictive factors of the positive cultures in patients with acute diarrhea. Methods: A total of 13,327 patients who underwent stool cultures caused by acute diarrhea in a tertiary center from Dec. 2004 to Nov. 2014 were reviewed. The stool cultures were performed for enteric pathogens as follows: Salmonella, Shigella, Vibrio, Klebsiella oxytoca and Yersinia. The culture positive rates and the predictors for the positive culture were analyzed. The culture positive group was compared with the same number of culture negative group who were randomly selected among culture negative patients. Demographics, clinical features, and laboratory findings were compared between the two groups. Results: A total of 196 patients (1.47%) (102 males; mean age, 23.7±22.3 years) from 13,327 patients were diagnosed with positive stool culture. In 196 culture positive patients, Salmonella spp. (146/196, 67.7%) was detected most commonly, followed by Vibrio (38/196, 25.0%). In the univariate analyses, fever (>37.8 °C), vomiting, duration and frequency of loose/watery stool, and high hs-C-reactive protein (CRP) were significantly associated with the positive stool culture. Fever (odds ratio [OR], 2.12; 95% confidence interval [CI], 1.16 to 3.86; p=0.014), more than four loose/watery stool per day (OR, 3.59; 95% CI, 1.99 to 6.46; p 50 mg/L of hs-CRP (OR 3.16; 95% CI, 1.70 to 5.87; p < 0.001) were independent risk factors for the positive stool culture in multivariate analysis. OR in patients who had all the three factors was 6.99 for positive stool culture (95% CI, 2.86 to 17.13; p < 0.001). Vomiting (OR, 0.33; 95% CI, 0.18 to 0.59; p < 0.001), on the other hand, was negative predictive factor. Conclusion: The positive rate of stool culture in patients with acute diarrhea was very low (1.47%). Fever, frequency of loose/watery stool and high CRP are the independent predictors for positive stool cultures. These findings will likely lead to more discerning and cost-effective utilization of stool culture testing by clinician." @default.
